Product Summary

The FT245BL is a USB FIFO (USB-Parallel) I.C., it provides an easy cost-effective method of transferring data to / from a peripheral and a host P.C. at up to 8 Million bits (1 Megabyte) per second. Its simple, FIFO-like design makes it easy to interface to any microcontroller or microprocessor via IO ports.To send data from the peripheral to the host computer, simply write the byte-wide data into the module when TXE# is low. If the (384-byte) transmit buffer fills up or is busy storing the previously written byte, the device keeps TXE# high in order to stop further data from being written until some of the FIFO data has been transferred over USB to the host.
